YARN AND FABRIC MADE THEREFROM Filed Feb. 26, 1956 Qvwcwhon} RALPHC. ANOER5ON Patented Apr. 20, 1937 YARN AND FABRIC MADE THEREFROM Ralph C. Anderson, Charlotte, N. 0. Application February 26, 1936, Serial No. 65,861

Y Claims.

This invention relates produced therefrom and more especially to a thereof saponified so as to have anafiinity for a cotton dye, leaving the untreated portions without an affinity for the cotton dye but retaining an aflinity for an acetate dye so that the yarn can be .used in circular knitting machines for the knitting of stockings and especially the tops of stockings to produce pattern efiects therein when the stocking is dyed.

It is an object of this invention to provide a .yarn having a cotton strand and an acetate strand twisted together with intermittently spaced strand being previously in knitted fabrics.

It is another object of this invention to provide a yarn comprising two strands twisted together with one of the strands having an aflinity for a certain'dye and with intermittently spaced portions of the other strand having an aifinity for the said certain dye while the other portions of said other strand do not have an aflinity for said certain dyes but fora difl'erent type of dye.

It is another object of this invention to provide a pattern eiTect in a knitted fabric such as the top of a stocking by means of twisting two strands together to form a yarn, said strands being of diflerent materials and one strand having intermittently disposed portions thereof treated to render it subject to be dyed with the same dye which is used for. dyeing the other strand so ;hat a twisted strand can be produced having inermittently spaced portions thereof subject to me type of dye while one of the strands in the ther intermittently spaced portion will have an .flinity for another type of dye so that the yarn an be knitted into a stocking and the stocking ross dyed to produce the desired pattern efiects. Some of the objects of the invention having een stated, other objects will appear as the escription proceeds when taken in connection ith the accompanying drawing, in which:- Figure 1 shows a stocking knitted from my new we of yarn;

Figure 2 is a developed view of the upper portion Figure 1;

Figure 3 is an enlarged detailed view of a porm of the yarn;

Figure 4 is an enlarged detailed view of a portion of the knitting in the upper part of the stocking shown in Figures 1 and 2.

In preparing this yarn, I take an ordinary twister frame and twist two strands together therein. One of these strands, let us say, is repre- 5 sented by reference character I 0 and is a cotton strand. The other strand II, for example, may be an acetate strand. Portions ll of the strand H are saponified so that these portions have an aifinity for a cotton dye. The other portions lZa of the acetate yarn are not saponified and therefore do not have an afiinity for a cotton dye.

Referring to Figure 3, it is there shown where the portion I5 is composed of the cotton strand and. the saponined portion l2 of the acetate yarn twisted together. The portion I6 is the cotton strand and an unsaponified portion of the acetate strand twisted together, whereas, portion I! of the yarn is similar to I5 and comprises another portion of the saponified acetate and the cotton yarn twisted together. The length of the saponified portions can be as desired, but I can produce a very good pattern efiect by having the lengths of saponified sections sufllclent so that in the twisted yarn a spot of the saponified and unsaponified portions will be long enough in a circular knitting machine knitting a particular size, of stocking, to furnish enough yarn in a particular portion to knit three-fourths the way around the stocking or three-fourths course. This makes a stocking.

Let us suppose that the portions II, which are treated would dye black, whereas, the unsaponifiedlength ll of portion I 6 would remain white. Therefore, we can see that in knitting theribbed top l8 of a stocking, the portion IGa in Figure 2 would go three-fourths the way around the stocking to the point a, and then the portions Ila of yarn would begin and continue 40 another three-fourths the way around the stocking to the point b, and then another portion lib would begin and go three-fourths the way around the stocking to point d, tion llb would begin and go to the three-fourths around the continue throughout the knitting.

This would produce'a spiral stripe around the top portion of the stocking due to the saponifled and unsaponified portions of the yarn being susceptible to different dyes, and whereby crossdyeing could be carried out either in the finished stocking or in the yarn before knitting.

Of course, it is evident that other desired pattern effects or. stripe eflects can be produced but spiral stripe around the point e, or 45 stocking and this would seven .inches long tions and the saponified sections to produce the desired results.

In the drawing and specification there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only, and not for purpose of limitation, the scope of the invention being set forth in the appended claims.

I claim: I

i. That method of making stockings which to be subject to a dye which will not dye the unsaponifled portions, determining the length of the saponified portions so that a saponifled portion will knit more than one-half of a course and the unsaponifled portions will knit a portion of a course equal in length to theportion'of a course knitted by a saponified portion, so that when the knitted stocking is dyed a spiral striped effect is produced by the overlapping of the saponifled and unsaponifled portions.

2. That method of producing a stocking which comprises spinning a cotton strand, then saponifying alternately disposed portions of an acetate strand, then twisting the two strands together, the saponifled portions having a length which is equal to the length of the unsaponified portions, each portion being sumcient to knit more than half a course in a. stocking, then cross-dyeing the stocking to produce a striped effect.

3. That method of knitting a. stocking which comprises preparing an acetate yarn having alternately disposed saponified and unsaponified portions of equal length, a saponifled portion and an unsaponifled portion being suflicient to knit more than one complete course ,so that when the stocking is dyed a striped effect is produced in the stocking due to the overlapping of the saponifled and unsaponlfied portions.

4. A circular knit fabric knitted from a yarn which has been previously treated to cause alternately disposed contiguous portions of equal length to have an aillnity for two different dyes, a pair of said contiguous portions having a' total length which is greater than the length of a course in said fabric whereby the overlap of said portions in the knitted fabric, when the same is cross-dyed, will produce a striped effect in the fabric.

5. A circular knitted fabric knitted from an acetate yarn having alternatively disposed portions thereof saponified, the saponified and unsaponified portions being of equal length and being proportional in length to the circumierence oi the knitted fabric, each portion being long enough to knit more than half a course to thereby'produce a striped effect in subjected to a dyeing operation.
